Only thing not show is the foam ring that sits on the air cleaner base. Seals the base to the hood.

How thick is gasket? I would think you would get better seal by leaving a bigger gap, like up to half inch. Then use about 3/4 to an inch closed cell foam and let it compress. Vs. Try to get it close/precise and use thinner gasket.
